How to repair Windows Server 2022 installation with DISM
In this tutorial, you will learn how to repair a Windows Server 2022 installation using DISM (Deployment Image Servicing and Management). DISM is a powerful command-line tool for scanning and fixing issues in Windows images, including server operating systems. If your Windows Server 2022 is experiencing problems, the DISM /restorehealth command can be an effective solution. Here’s a step-by-step guide:
Preparation:
- Ensure you have a backup of your data. For virtual machines, consider creating a snapshot.
- Mount your Windows Server 2022 ISO as a drive and note the drive letter.
Steps:
- Open Command Prompt as Administrator: Start by launching Command Prompt with administrator privileges.
- Scan for Health Issues: Enter the command:
dism /online /cleanup-image /scanhealth
This will scan your system for any issues.
3.Check the Health Status: After the scan completes, run:
dism /online /cleanup-image /checkhealth
This checks the health of your Windows image.
4. Restore System Health: With your ISO mounted, use the following command (replace d: with your ISO drive letter if different):
dism /online /cleanup-image /restorehealth /source:WIM:d:\sources\install.wim:2 /limitaccess
This restores the system health using the Windows Server 2022 image.
5. Repair Additional Corruption: Next, run:
sfc /scannow
This scans for and repairs any additional file corruption.
6. Restart and Update: After completing these steps, restart your server. It’s advisable to run Windows Update post-restart to ensure all components are up to date.

Hi Patrick, my VM is not allowing me to get to the Command Prompt at all. As soon as I ‘start’ it on Hyper-V and ‘connect’ to it, the very initial screen says “Boot failure. Reboot and select proper Boot device or Insert Boot Media in selected Boot Device”.
Hello,
If you have hyper-v secure boot enabled, turn it off and mount the window server ISO into the VM’s cd/dvd to boot from.
Thank you,
Patrick Domingues
If your using Datacenter Edition or Core Installation you have use another Image Index (i.E. 4 for Datacenter). Otherwise you will get error 0x800f081f (source not found).
Patrick,
I have a Windows Server 2022 that is stuck in the SFC “needing a system repair, please reboot server” mode. When I run sfc /scannow the error says a system repair is in progress, please restart server. The problem is that the component store was corrupted and the sfc /scannow was run before dism was used to repair the image. The image is now repaired and all dism commands provide good results, but sfc is still stuck. I have found that no windows updates will complete, the server roles and features are not displayed, and msconfig always reverts to selective startup.
I have a good image of the system state, but server restore requires that I restart the server in DSRM mode (active directory on the volume) but I am remote to the server (about 350 miles).
i was wondering if you had any ideas to clear the sfc so that I could run it again with the repaired image store.
